The quote you’re looking for is from The Dark Knight Rises : Bane says, “You merely adopted the dark; I was born in it, moulded by it.”

The rest of the line is:

  • “Oh, you think darkness is your ally.”
  • “I didn’t see the light until I was already a man.”
  • “And by then, it was nothing to me but blinding.”

It’s often misremembered in rough form because the idea is about Batman thinking he owns the darkness, while Bane says he truly belongs to it.
